运动心电图ST改变对冠心病的诊断价值,因其敏感性及特异性较低,成为医学界长期争论的议题。50年代Brody发现左室R波随左室容量增加而增高。此为“Brody效应”。根据此学说,有人将R波振幅指数(△R)作为冠心病诊断指标。本文以△R为指标分
Exercise ECG ST changes on the diagnosis of coronary heart disease, because of its low sensitivity and specificity, has become the subject of long debate in the medical profession. In the 50s Brody found that left ventricular R wave increased with increased left ventricular volume. This is the “Brody effect.” According to this theory, some people will be R wave amplitude index (△ R) as a diagnostic indicator of coronary heart disease. In this paper, △ R points for the index
